A covalent bond is a chemical bond formed by sharing electron pairs between two atoms. It can be a single bond, double bond, and triple bond, depending on the number of electron pairs shared between atoms.
Carbon belongs to group 14, and hence, it has four valance electrons. According to Lewis-Kosell theory, an atom tries to achieve the nearest noble gas configuration by bonding. It can be achieved either by gaining or losing electrons or sharing electron pairs. The nearest noble gas configuration means that an atom should have eight electrons in its outermost shell.
It is difficult for any atom to lose or gain four electrons, and hence, they share the electrons and form a covalent bond.
